Revolution drops off line every few mins

[Barryhenn]

I know it's an old phone and i'm tired of upgrading for not much better.

Why does the revolution continually lose the internet connection?  Every few minutes then it reconnects.

I have other phones in the house and they do not do that, so it's not my router etc.

It happens when I'm not connected to the Wi fi as well as being connected.

Often times I get no bars and no appearance of communications.  If i turn off the phone and when it boots up then it works okay for another hour or so although it still drops off line when surfing the web.
